SEGMENT GATE.

Application filed April 11, 1922.

T 0 all whom it may concern Be it known that I, THnonoR Bnci-inn, acitizen of Germany residing at Gustavsburg, Germany, have inventedcertain new and useful Improvements in Segment Gates (for which I havefiled application in Germany April 28, 1920) of which the following is aspecification.

My invention relates to well known segment gates consisting of two partsof which the upper segment leaf lies behind the lower and can be loweredunder the upper edge of the upper retaining plate, but a constructionaldrawback lies in the fact that the supporting arms of both segmentleaves which swing around the same pivot have to cross each other at thelowering of the upper segment leaf which causes difiiculties, especiallyin case of large segments and segments of broad spa-n because it is noteasy to give the open frame of the bracings a sufficient carryingcapacity.

It is possible to avoid this dificulty by adopting the Way which hasalready been suggested for old and small segments viz. that thesupporting arms are placed beside each other and thus a crossing of eachother is no longer necessary. This arrangement has, however, the greatdisadvantage that the two supporting arms owing to their breadth andposition can no longer be placed in the cavity of the lateral masonry orpier and therefore the arms are subject to damage through ice orfloating materials of any kind. Another way Would be to deepen thelateral cavities accordingly, but this would require a considerableincrease of Specification of Letters Patent.

the breadth and thus increase immensely the costs of the masonry.

Following the invention these difficulties are avoided in such a mannerthat the upper segment leaf is journalled to swing on a special pivotarranged on the supporting arm of the lower segment.

The drawing shows such a segment gate in cross section. The lowersegment leaf a is supported through its bracings 2) against the bearing0 and can swing around the pivot (Z. The upper segment leaf e turnsaround the supporting arm f and the pivot g which is arranged on thelower segment leaf. As may easily be seen from the drawing thearrangement of the bracings of both segments do not interfere with eachother therefore the bearing 0 as well as the bracings b of the lowersegment can be made considerably simpler as under the usual arrangement.The slight difference of the curve radius of the upper and lower segmentis of no importance to the operation and construction of the gate.

lVhat I claim is:

A segment gate consisting of two parts be ing arranged one above theother in such a manner that the upper segment leaf is journalled toswing on a special pivot arranged on the supporting arm of the lowersegment leaf.

In testimony whereof I aflix my signa ture in presence of two witnesses.
